uRADMonitor MODEL INDUSTRIAL is built for demanding environments with industrial gas sources. Its gas measurements come from electrochemical cells, consumable sensors that react chemically with the target gas. That chemistry is what makes them accurate, and also why they wear out: a cell lasts about two years before it must be replaced to keep the readings trustworthy.

Which cells your MODEL INDUSTRIAL has

MODEL INDUSTRIAL carries four electrochemical cells, chosen at order time for the site. Many gases are supported, but the most common configuration is:

  • Ozone (O₃)
  • Nitrogen dioxide (NO₂)
  • Sulphur dioxide (SO₂)
  • Carbon monoxide (CO)

Other gases (for example H₂S) can be fitted on request. Check your order or your device page to confirm exactly which four cells your unit carries. The odour, noise, particulate and environmental sensors are not electrochemical and are not covered by the two year limit.

Why electrochemical cells age

The electrolyte is slowly consumed and can dry out, lowering sensitivity; the clean-air baseline drifts; and the response slows, so short peaks are under-reported. This is normal wear, not a fault, and it is corrected by replacing the cell. In an industrial setting, where the whole point is to catch real exceedances, keeping the cells current matters more than anywhere else.

How to tell your cells are due

Your device page shows a cell service counter running from the first reported data (or last recorded service) to the two year limit. When the bar turns red, the cells are past their service life. Watch also for a channel sitting at a flat or unusual baseline, or no longer tracking events you expect from the site.

Replacing the cells

To refresh the four cells, request an RMA. We fit fresh cells in your configuration, verify the unit, and return it ready for another two year cycle. For sites with several INDUSTRIAL units, we can plan the refreshes together to minimise downtime, contact us through the RMA form.

After replacement

Once the service is recorded, the counter resets from the replacement date, giving a fresh two year window. Regular refreshes are what keep an INDUSTRIAL network dependable for compliance and early warning.

Open your device page for the exact counter and configuration, or start an RMA.
